Heathkit SG-6 User Manual

IN CASE OF DIFFICULTY
1. Recheck entire wiring. Follow each lead and color it on the pictorial with colored pencil.
Most cases of difficulty result from wrong or reversed connections. (Often having a friend
check the wiring will divulge an error being consistently overlooked.)
2. Be sure that the output is connected to the tip connection of the jack and that the output cable
is not shorted inside the phone plug.
3. Check the voltages. The table below lists voltages from pins of the 6C4's to chassis. All
readings are DC except where indieated. These voltages were measured with an 11 megohm
input vacuum tube voltmeter. A normal variation of ± 15% is to be expected.
